On the official website of the New South Wales Government there's a tool that allows you to explore the popular baby names in NSW over the past 100 years.

By typing any name into the 'Type a name' field you see its ranking from 1900 to 2011. By type any letter into the 'Type a name' field, for example, type 'A' (as below) to see names starting with 'A', type 'Al' to see names starting with 'Al'. You can then hover over the visualization and click a name for more information. Blue is for boys and pink is for girls.

The USA Social Security Administration official website has a really powerful tool that will show you the popularity of any name you enter. It shows the ranking of the name for 14 years. Rank 1 is the most popular, rank 2 is the next most popular, and so forth. Baby name data are from Social Security card applications for births that occurred in the United States.

When I entered my name "Daniel", this was the result:

This is the result when I entered "Jacob":

Jacob has been the top boy baby name in the United States for the past 14 years, amazing!
